[英]Scala Test “Unsupported major.minor version 52.0” after sbt clean compile with JDK7
在Stackoverflow上肯定有數百種此類錯誤，但是沒有一個適用於我。 我確切知道此錯誤是什么意思，但是我的事實是：
我不知道為什么運行此測試時會出現此錯誤。 用Java 8（版本52）如何以及在哪里編譯。
任何理智的來源現在都將受到歡迎。

Intellij從哪里獲得此版本52.0？ 有沒有我沒看過的地方？ 為什么只有這個測試？
我不知道為什么運行此測試時會出現此錯誤。 用Java 8（版本52）如何以及在哪里編譯。
該錯誤確切告訴您問題org.jetbrains.plugins.scala.testingSupport.scalaTest.ScalaTestRunner類： org.jetbrains.plugins.scala.testingSupport.scalaTest.ScalaTestRunner 。 它不在您的項目中，而是IDEA的一部分。 因此，它是在構建IDEA時編譯的，並且您項目的編譯設置不會影響它。
盡管給出了這個信息，但我不明白為什么“其他測試可以在IDE中正常運行”。
同樣，我不相信“在JAVA_HOME = jdk7時重新下載所有內容”會有所幫助； 下載的jar將是相同的，並且需要編譯它們所需的Java版本。
相反，您需要分別研究每個依賴項（及其傳遞的依賴項），並可能下載它們的源代碼，嘗試使用Java 7重新編譯它們（必要時進行修改）並在本地發布。
不知道這是否仍然有幫助。 我將“編輯配置”中的JRE切換為1.8（顯然IntelliJ使用JRE 1.8，ScalaTestRunner也以此編譯），並且測試成功運行。
